NBC's converage of the NBA blew chunks. When watching the Lakers for the past umpteen years I'd just mute it and turn on the radio.
Now, not that ABC is much better, (and their floor-cam looks posed to be in for a XXX rating before long) but ESPN is doing awesome coverage mostly. I've only seen 6-7 ABC presentations (think thats all theere's been) and have been impressed by the visual quality and euqally unimpressed with the commentators.
TNT coverage is awesome, specially the half-time and pre/post game shows with Barkley and Co.
